Hmm my understanding is: ARA is naturally occuring in egg yolk, but DHA is only in egg yolk of chickens fed a special DHA supplemented diet, so it's the same thing really unless you some how going through the chicken's system is helpful- it may be. I don't know That's the first I've seen of a product with that much non fish based ARA- which would be very helpful for my son's condition- awesome link. I have a couple of red flags going up with that company, based on that site so I need to do some research, but I'm excited about the prospect of not having to fuss so much about dietary ARA!
